My connection problem ended up being my cable. It worked fine for a long time then after I changed my headgasket it didn't work. I was freaking out. Cables seem to be a pretty common problem. Also make sure all of your diagnostic port's pins are locked in. Take a pair of needle nosed pliers, and...
I've read that it can be caused by a bad iac. I replaced mine with a tested good one and it still happens. I've looked at my ecu and I can't see any visible damage. I'll check my isc position on link when I get home. And my tb coolant lines are looped so I'm not sure how that effects the fiav...
Any luck finding out what was wrong? I've been having this exact problem for awhile. If I give it gas for about a minute or so it will hold an idle and be fine. Just curous if you found a remedy yet.
Then you put a water temp gauge down there.. I like to watch my gauge as well, so I probably shouldn't have said boost gauge in my initial post but it was the first thing to come to mind.
Well, you can put a temp gauge or other gauge that doesn't need too much monitoring down there lol. Its not too much different than looking down at your radio and driving..
With a bad o2 sensor the ecu will lock itself in open loop mode creating a very rich mixture to prevent damage to the motor. So order and install the new o2 first, because it says it's bad, and go from there. I had a similar issue and it solved it for me. So start there and see what you're left...
I borrowed an o2 sensor from a buddy of mine, until mine gets here on Saturday, and hooked it back up to the way I had it. It works so.. if it ain't broke don't fix it applies here. My car is in closed loop again but my wide-band keeps giving me 17:1 and up to --- so I've got a hunch my sensor...
the 1g's don't have a rear o2.. and I have the front o2 wire tapped. I want to say my problem might be because I didn't cut and butt my wideband and ecu together, I stripped the wire and tapped it that way. so it still runs to the front o2 female plug in the engine bay (which has nothing plugged...
If I'm not mistaken, shouldn't the o2 voltage should still cycle up and down even if the calibration is off? I will post a log when I get home.. and I had to order a new NBo2 so it will be here Saturday. I will most likely set it back up to how I had it before, for the simple fact that it works...
